The company, which competes with big players including IBM Corp., Hewlett-Packard Co. and McAfee Inc., has signed a dozen customers in the financial services, higher education and retail sectors, Willebeek-LeMair said.

John Vrionis, partner at Lightspeed Venture Partners, said his firm was impressed by Click Security's approach to stopping cyber threats.

"The business of global cybercrime, by some estimates, now exceeds $300 billion annually. Traditional security defenses are clearly not getting the job done," he said in a statement. "We believe Click Security has developed a unique approach to providing real-time visibility into the unknown -- representing a game changer for organizations looking to take back their networks."
